create_database · Ploi MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_database does on Ploi MCP Server

AI agents use create_database to create or update resources in Ploi MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ploi MCP Server environment.

WHY IT NEEDS A POLICY

Why create_database needs a policy

Creating a database is a Write operation—it modifies infrastructure state by adding a new database resource, but the action is reversible (can be undone via delete_database). It's not Destructive because it doesn't delete or irreversibly overwrite data. It's not Execute because it doesn't run arbitrary code or scripts. It's not Financial.

From the tool's definition Tool is named 'create_database' and description states it 'Create[s] a new database on a server' with optional user/password configuration. This is a reversible data structure creation operation.

Verdict

create_database Rate-limited

create_database stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

What risk level is create_database? +

create_database is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_database? +

Yes. Add a rate_limit block to the create_database rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_database completely? +
